Cantor could apparently demonstrate that there were as many points in a one-inch line as there were in all of space. He had taken a giant leap into the unknown and found something unique, something that nobody had ever considered before him, but his critics, who were many and varied, argued that he had simply gone too far. His infinities, while undoubtedly interesting, could never be considered objects for serious mathematical study. However, Cantor was armed with a proof that seemed completely airtight. “I see it, but I don’t believe it!” 79he wrote to a close friend when he had finished it, and his biggest problem, from then on, was that so many others were equally unable to accept this new and confounding article of faith.
